What is sperm motility?

In brief:
Sperm motility

Grading scale:
0 = no motion.

1 = some head or tail movement, but no forward progress.
2 = feeble forward progress, not likely fast enough to swim against the current through the fallopian tube.
3 = rapid forward progression
4 = frenzied swimming (rarely seen in human sperm).
